WebFeb 19, 2024 · Creep is a type of deformation that occurs in materials subjected to a constant load over time. The deformation is permanent and results in a change in the shape of the material. Creep is most commonly observed in metals, alloys, and polymers. It occurs when the molecules within the material are forced to move past one another. is anyone from love island 2 still together
